Is it possible to use the IP whitelist middleware with TCP Proxy?

Support

I’m trying to add an IP whitelist to a TCP proxy API but the setting seems to be ignored.

{
    "name": "dev_sftp_proxy",
    "api_id": "dev_sftp_proxy",
    "listen_port": 2222,
    "protocol": "tcp",
    "certificate": [
    ],
    "proxy": {
        "target_url": "tcp://192.200.214.95"
    },
    "org_id": "dev_live",
    "enable_ip_whitelisting": true,
    "allowed_ips": [
         "10.20.0.0/14"
    ]
}

Is it possible to achieve this with tyk-gateway?
